在INIT方法中DJANGO MODELFORM中所有字段的属性设置

Question

我有一个django modelform，其中我以 __init__()方法的形式设置某些表单属性。

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
        exclude = ['datecreated', 'datemodified']
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['field1'].widget.attrs['class'] = 'class1'
        self.fields['field2'].widget.attrs['class'] = 'class1'
        self.fields['field3'].widget.attrs['class'] = 'class1'
        # override Google Chrome field error issues making form unfocusable
        self.fields['field1'].required = False
        self.fields['field2'].required = False
        self.fields['field3'].required = False

是否有的属性中包含的所有字段中都不编写每个字段。

self.fields是一个普通的dict，您只能迭代其值：

for field in self.fields.values():
    field.widget.attrs['class'] = 'class1'
    field.required = False
